We have observed and collected unusual specimens of what we recognize as undescribed types of the genus Atolla over the past 15 years. Of these, there appear to be three potentially different types. One of these has now been genetically sequenced and compared both morphologically and molecularly with five other Atolla species that have been found in the eastern Pacific. This new variant is so morphologically distinct from other previously described Atolla species that we believe it can be described as a new species, Atolla reynoldsi sp. nov. This species along with two additional types may comprise a new genus. It is also clear that a more accurate and diagnostic morphological key for the genus Atolla needs to be developed. This paper will also provide some potential starting points for a new key to the genus.
